Role of PAL and PPO Enzyme Activity in Host Pathogen interaction of Chickpea (Cicer Arietinum L) Root Tissue Infected with Fusarium Wilt

Role of PAL and PPO Enzyme Activity in Host Pathogen interaction of Chickpea (Cicer Arietinum L) Root Tissue Infected with Fusarium Wilt



Rathod P. J,D.N Vakhariya 



In this study, changes in the activities of
Phenlylalanine ammonialyase (PAL) and polyphenol oxidase (PPO) during
development and stages of wilt (Fusarium oxysporum Schlechtend.:Fr.
f.sp. ciceri (Padwick) Matuo & K. Sato) disease infection in
chickpea(Cicer arietinum L) were investigated. During the early stages
of disease development, at pre-infectional stage (S1), cultivars did not
show any significant change in PAL activity. The activity was
significantly increased at infectional stage (S2) as compared with pre
infectional stage (S1). Susceptible cultivars had the lower value of PAL
at infectional stage (S2). However, at S2 stage cultivars GG-4 and
JCP-27 were at par. At post infectional stage (S3), the activity was
found to be increased in the all cultivars as compared to infectional or
mid growth stage and the resistant and tolerant cultivars were at par.
Susceptible cultivars (JG-62 and GG-4) had the lower activity as
compared to the resistant and tolerant cultivars. The resistant
cultivars WR-315 and JCP-27 revealed higher level of activity, the level
of activity significantly increased marginally during infection. In
the present experiment significantly higher activity in infected plants
grown in sick plot also suggested that polyphenol oxidase might be
involved in oxidation of phenolics in susceptible cultivar (JG-62).
These observations suggest that the increase in PAL and PPO activities
has an important role in disease resistance mechanism.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
